Speaking of SSD upgrade, I happened to have a spare 256GB PCIe SSD from 2013 11" MBA and I just got myself a new (never opened) 2013 11" MBA with base config (128GB).
I know swapping out SSD and OS install is dead simple, but my main concern is the warranty. I've called the Apple Store and confirmed that it DOES void the warranty AND Apple Store would not offer to swap the SSD that was pulled out from the exactly the same model from the same year(2013 11" MBA). Sounds really stupid & silly but that is what they said. Honestly, I never pay for "computer service & repair" fees, but I am wiling to pay however long it takes them to swap the drive with their usual 1 hour rate (though it should literally take like 10 minutes or less) JUST to keep my warranty.
Anyway, I was curious if anyone here knows whether I can just pop in my 256GB SSD in and when my MacBook needs to be serviced, would swapping out SSD to the original one not void the warranty? I know it's "my choice" to do such thing or not, but I'm just throwing this out there see if anyone had the similar experience or know anything about it.
On the plus note I know this sounds really silly, but would they be able to find out via software log by any chance? I guess there is no way for them to find out via hardware, unless there's a warranty sticker or it clearly shows that the screw that's holding the SSD is all stripped down or something.
Thanks in advance for any help!
